To all whom it may concern:

Be it lmown that 1, JOHN E. GRAPER, a citizen of the United States,residing at Fort Atkinson, county of Jefierson, and

State of Wisconsin, have invented new and useful Improvements inElevators for Corn Huskers and Shredders, of which the following is aspecification.

My invention relates to improvements in elevators for corn huskers andshredders and the like.

The object of my invention. is to provide a more eflicient and durabledevice for simultaneously separating the shelled corn from the husks andshredded stalks as the same are being elevated from the husking rollersto the pneumatic tubes or other mechanism.

by which the husks are conveyed to the place of discharge.

My invention is further explained by reference to the accompanyingdrawings, in Which- Figure 1 represents a side view of my elevator as itis used in connection with an ordinary corn husker and shredder, thesides of the corn husker and shredder being broken away, the better todisclose the construction of my improved elevator. Fig. 2 is a plan viewand Fig. 3 is a side view of a portion of the elevator removed from thehusker and shredder.

Like parts are identified by the same reference numerals throughout theseveral views.

My elevator comprises, among other things, an endless series ofhorizontally ar 1, which bars are each support ranged bars ed at theirrespective ends from an endless chain 2, it being understood that asimilar chain to that shown is used at the opposite end of said bars,and these chains 2 each comprise a series of separate links 3. The links3 are each provided at one end with hooks 4, and between their ends withapertures 5, in which said hooks engage, whereby a plurality of linksare adapted to be interlocked together to form said endless chain 2 at'each end of said horizontal bars 1. The several links 3 are provided attheir inner sides with pockets 6, for the reception of the ends of saidhorizontal bars 1, and said bars are retained in said pockets by screws7, which are inserted through said links into .said bars as shown inFig. 3. One of the corners 8 of said horizontal bars 1 is removed,whereby the upper surface (reference being had to the upper side of Fig.3) inchnes downwardly and rearwardly from the front edge 9 of said bars,whereby the corn or other grain, which is being elevated with the husksis free to drop rearwardly and downwardly and pass between the severalbars 1 oi the elevator, when such grain descends of its own gravity uponthe downwardly inclined plate 10, when the same may be carried away by aconveyer 11 to the side of the machine. the upper edges 12 of said barsare provided with a plurality of pins 13, the pins of one her beingpreferably arranged to alternate with the pins of the two next adjacentbars above and below, as shown in Fig. 2. Theres ectivc chains 2,together with the series 0' transverse bars and pins, are adapted to besupported at their lower ends from a driving shaft 14 upon a pair ofsprocket wheels 15, and at their upper ends from a shaft 16 upon thesprocket wheels 17 when, as said shafts and wheels revolve, the teeth18, of said sprocket wheels operate in the apertures 5 of said chains. I

I am aware of the fact that sprocket wheels and sprocket chains are notnew; also that it is not new to connect chains'together by transversebars, but invention herein is predicated more especially upon thepeculiar construction of said bars, in which one of the corners 8 isremoved, leaving the bars substantially triangular in cross-section,while each of said bars is provided with a plurality of vertical pins13, the pins of one bar being arranged to alter-' nate with the pins ofthe two next adjacent bars, said bars, being adapted by their peculiarshape, to facilitate the separation of the shelled corn from the husks,while the pins 13 cotiperate with the bars in elevating the husks froin'the lower to the upper end of such conveyer.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

l. In an elevator for corn huskers and shredders, the combination of apair of endless sprocket chains, a pair of sprocket wheels, located atthe respective upper and lower ends of said chains, a shaft forrevolubly supporting each pair of sprocket wheels, a series oftransverse bars substantially triangular in cross section, means forconnecting the respective ends of said bars with said sprocket chains,and a series of ill? Add

- pins connected with and projectilig laterally from each of said bars.

- 2. In an elevator for corn huskers and shredders, the combination of apair of end"- less sprocket chains, the respective links of said chainsbeing provided with pockets for the reception of transversely arrangedbars carried by said chains, a pair of sprocket wheels, located at therespective up er and lower ends of said chains, a shaft or revolublysupporting each pair of sprocket wheels, a series of transverse barssubstantially triangular in cross section, having their respective endslocated in, the pockets of the links of said chains, each of said barshaving its lower outer corner removed to facilitate the passage ofshelled corn between them, and a series of pins connected with andprojecting laterally from each of said ars.

3. In an elevator for corn huskers and shredders, the combination of apair of endless sprocket chains, each comprising a series of links, eachlink being-provided with a pocket for the reception of the end of one ofthe transversely arranged bars, a pair of sprocket wheels, located atthe respective upper and lower ends of said chains, a shaft forrevolubly supporting eachpair of sprocket wheels, a series of transversebars substantially triangular in cross section, having their respectiveends located in the kets of the links of said chains, each 0 said barshaving its lower outer corner removed to facilitate the passage ofshelled corn between them, a series of pins connected with each of saidbars, the series of pins of one of said bars being located atintermediate points between the pins of the two next :adjacent barsabove and below;

In testimony whereof I aflix my signature in the presence of twowitnesses.
